Preheat oven to 420 degrees F. Thaw puff pastry in refrigerator
For the filling: Melt butter in a pan. Add the apples and toss so they are covered with the melted butter. Add brown sugar, rum extract, pumpkin pie spice and apple cider. Stir over heat until thick.
Lay 1 sheet of puff pastry flat on a cutting board. Cut puff pastry with Halloween shaped cookie cutters like bats, pumpkins and ghosts. Place cutout shapes on an ungreased cookie sheet. Make sure there is enough room between shapes for them to puff-up. Bake in the oven for 20 minutes.
When puff pastry has been baked carefully cut each shape in half like a sandwich. Spread apple butter on bottom half of puff pastry. Layer apple filling on top of the apple butter. Put whipped topping on top of apple filling. Place top half of puff pasty on whipped cream to complete the sandwich. Sprinkle with powdered sugar.
